2026 Cougar Half-Ton23MLE

The Cougar Half-Ton 23MLE is the shortest fifth wheel in Keystone's Cougar Half-Ton line, and that is its whole reason for being: it brings the stability and the bi-level interior of a fifth wheel down to a sub-28-foot length and a 1,275-pound pin weight that a properly equipped half-ton truck can carry. A single slide opens the mid-coach living area, a front bedroom sits up in the raised nose over the truck bed, and the layout keeps the kitchen and living room on the main floor — the most approachable way into fifth-wheel towing the Cougar line offers.

For shoppers new to fifth wheels, the difference from a travel trailer matters: the kingpin sits over the truck's rear axle rather than behind the bumper, which makes for a more planted, less sway-prone tow, and the raised front bedroom frees the main floor for living space. The 23MLE carries the full Cougar Half-Ton build — a five-sided aluminum superstructure, laminated HyperCore composite sidewalls, a walkable one-piece TPO roof under a lifetime limited roofing warranty, and a heated, enclosed underbelly under the Climate Guard package — on tandem 4,400-pound axles with Goodyear Endurance E-rated tires.

At 7,745 pounds dry against a 10,075-pound GVWR it leaves a healthy 2,330 pounds of payload, and its 1,275-pound dry pin weight is low for a fifth wheel — but pin weight, like tongue weight, rises as the trailer is loaded, and a fifth wheel's pin weight lands directly on the truck's payload, so it must be matched honestly to a half-ton's rear-axle and payload ratings. At 12′7″ tall it clears most obstacles a taller fifth wheel would not. For couples who want a fifth wheel's tow manners and interior without a three-quarter-ton truck, the 23MLE is the line's natural starting point.

Keystone's Cougar splits into two families. The full-size Cougar is the heavier flagship fifth wheel — 5,100-pound axles, H-rated tires and roughly 13′4″ of height. The Cougar Half-Ton line is engineered to be towable by a properly equipped half-ton truck, and Keystone offers it as both a fifth wheel and a travel trailer — lighter 4,400-pound axles, Goodyear Endurance tires, and lower pin or tongue weights. The 23MLE on this page is highlighted; each other profiled plan links to its own page. The full Cougar catalogue runs to dozens of floorplans across both families; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.
